What is the anatomical and clinical importance of the piriformis muscle?
Acts as a boundary for identifying nerves.
The sciatic nerve often passes inferior to the piriformis muscle, however it can pierce through the muscle.
If the piriformis muscle was to become inflamed it could damage the nerve causing pain down the lower limb.

What is the anterior cruciate ligament?
Travels from the Intercondylar tibia plateau to the posteriomedial aspect of the lateral femoral condyle

Makes a popping sound when broken.
What is the medial collateral ligament?
Also knwon as the tibial collateral ligament.
Stabilises the knee joint when standing
What is the lateral collateral ligament?
Also known as the fibular collateral ligament
Maintains knee joint stability through range of motion
Is wider and flatter than the medial collateral ligament.
What are the lateral and medial miniscus of the knee?
Fibrocartilogenous bands, create 4/5th of a circle.
Widen and deepen the tibial articular surface making it more bowl-shaped to easier fit the femoral condyles, stabilising the joint.
Note the medial meniscus is larger and thicker.
What collateral ligament in the knee is the most likely to be injured and why?
Tibial collateral ligament.
Most force that injurs a knee comes from the lateral side hence forces the knee to bend medial braking the medial collateral ligament that is located on that side.
What meniscus is most likely to be injured and why?
The medial miniscus
Is larger in order to fit the larger medial femoral condyle, hence is subject to more friction so the meniscus is more likely to tear or be worn down.
What is the knee joint capsule?
Surrounds the deep ligaments of the knee.
Is made of an inner synovial membrane and an outer fibrous layer.
Encloses the articular ends of the knee joint.
Provides stability to tendons and ligaments
What are bursae?
Sac-like structures made of the synovial membrane that protrude through gaps in the fibrous layer of the knee joint capsule
Reduce friction by producing synovial fluid
Can become inflammed
What is the function of the oblique popliteal ligament?
Prevents hyperextension of the knee
What is the function of the anterior ligament of the fibular head?
Aids attachment of the fibula to the tibia.
What is the function of the medial and lateral patella retinaculum?
Stabilise the patella in position
What ligament does the patella lie within?
The patella ligament
Also the quadriceps femoris tendon
What does the tibial tuberosity act as an attachment site for?
The patella tendon hence indirectly the quadratus femoris tendon, allowing the quadmuscles to flex the leg at the knee joint
Draw a diagram of a simplified synovial joint.
